Product details

Industrial temperature range and package

Rated for -40°C to 85°C ambient, the DS1811R-10+T&R fits industrial control, outdoor telecom, and factory-automation environments where the board sees temperature swings. The SOT-23-3 package is a three-pin surface-mount footprint that takes minimal board area — useful when the supervisor is placed close to the monitored device's reset input to keep the trace short.

Lifecycle and sourcing posture

Maxim lists the DS1811R-10+T&R as Active with ROHS3 compliance.

Frequently asked questions

What is the exact reset threshold voltage of DS1811R-10+T&R?

The DS1811R-10+T&R has a reset threshold voltage of 4.35V, making it appropriate for monitoring a 5V supply rail.

Does DS1811R-10+T&R have an active low or active high reset?

The reset output is active low with an open-drain structure, so it pulls the reset line low when the monitored voltage falls below the threshold.

What is the difference between DS1811R-10+T&R and DS1811R-20+T&R?

Both are EconoReset supervisors in the same SOT-23-3 package with the same active-low, open-drain output and 100ms timeout. The difference is the threshold voltage — the DS1811R-10+T&R triggers at 4.35V, while the DS1811R-20+T&R uses a different threshold (not specified in this record). Choose the variant whose threshold matches your rail voltage.

Is DS1811R-10+T&R compatible with 5V systems?

Yes, the 4.35V threshold is designed for 5V digital systems. The supervisor monitors the 5V rail and asserts reset when the voltage drops below that level, providing power-on reset and brown-out protection for 5V-powered logic.
